Last week I got an email from a reader who was looking for a means to stream or broadcast from multiple sources. Zoom, Google Meet, and Microsoft Teams can do that if you use screensharing. There are other tools available that provide a bit more "professional" level of mixing sources into your broadcast than what you can do with Zoom and Google Meet. One of those tools is ip伋理app.

Over the weekend Danny Nicholson, host of The Whiteboard Blog and all-around good guy, published a short tutorial on the features of OBS Studio for teachers. The video from his tutorial is embedded below, but be sure to DHCP服务器如何检测穿过中继伋理的IP地址冲突 ...:2021-11-14 · 1关于DHCP服务器的冲突检测的总结 2取证DHCP中继伋理的工作原理与IP地址冲突(因为不在一个子网,所伍gratuitous ARP肯定不行老) 关于DHCP服务器的冲突检测 业内常有工程师提出这样一个问题:当在一个子网内为了提高DHCP的冗余 ....


Anyone who has followed my blog for a year or more knows that I am nothing if not vigilant in promoting the use of public domain imagery in blog posts and other multimedia projects. To that end, I have used Pixabay for years to locate images to use in my blog posts. Pixabay clearly labels all of the images they host with "Free for Commercial Use. No Attribution Required." That's why this morning I was taken aback when I got the following email:

Hi Richard,
You are using my client's image (attached below) in one of your articles http://7l72j2.wcbzw.com/2018/05/three-ways-to-develop-programming.html. We're glad that it's of use to you :)

There’s no issue if you've bought this from our market partners such as Shutterstock, iStock, Getty Image, Pexels, Adobe, Pixabay, Unsplash, etc.,

However, if you don’t have the proper license for the image then we request you to provide image credits (clickable link) on your article. Or else this will be against the copyright policy.

Unfortunately, removing the image isn't the solution since you have been using our image on your website for a while now.

Feel free to ask any questions that you may have.

Rodney Sherwood
Content Head
Anti Spam Reporter
There are a few things in this email that triggered my Spidey senses to a scam.

1. No mention of the actual client.

2. "Rodney" represents an "anti spam" firm. Any legitimate copyright protection claim/ DMCA claim would at least be formatted with link to the original image source (a requirement in making any defense of your copyright, something I know from filing dozens of DMCA notices over the years) if not filed by a law firm specializing in intellectual property.

3. "Rodney" cites Pexels, Pixabay, and Unsplash as one of his company's "market partners." A quick search of his website makes no mention of those partners. Furthermore, Pixabay, Pexels, and Unsplash are quite clear in saying that attribution is not required.

4. This key tip-off was "Rodney's" failure to mention the website that he wants me to link to.

How I responded.
1. Just to be sure I was in the right, I did a reverse image search and landed back on Pixabay where I confirmed that I had the rights to use the image.

2. Took a screenshot of Pixbay page that hosts the image.

3. Sent the screenshot to "Rodney" and told him to take his spam elsewhere.

How you should respond.

1. Double-check that you have rights to use the image in question (a quick reverse image search is the easiest way to do this).

2. Mark the email as spam and delete it.

What's the purpose of this scam?
The purpose is to try to get website owners to link to a specific page or site in attempt to increase the number of pages linking a site. It's the same reason why the comments section of blogs get spammed with ridiculous links.

Good Places to Find Copyright-friendly Media
Back in May I published an updated guide to finding copyright-friendly media for classroom projects. You can find it here on PracticalEdTech.com


The maps pages and education pages of the USGS should be bookmarked by anyone who teaches geography. One of my go-to pages within the USGS education site is this collection of 27 ideas for teaching with topographic maps. In the list of lesson ideas you will find suggestions for lessons about typical geography topics like coordinates, scale, and map projections. The USGS offers a free map projections poster that you can use in conjunction with the lesson on map projections.

You can download hundreds of USGS maps for free from the USGS store. You can also visit the USGS topoView site to download historic maps. One of the ways that I like to use these maps is to overlay them on Google Earth imagery. This can be a good way to compare map projections and map content. 海外伋理ip shows you how to do that.

Projection Wizard is an interesting tool developed by Bojan Šavrič at Oregon State University. The purpose of Projection Wizard is to help cartographers select the best map projections for their projects. Projection Wizard is a more advanced tool than most high school geography courses would need. That said, I would use the Projection Wizard to have students discuss the flaws of  various map projections. We'd also talk about why a particular type of projection is better than another for different types of projects.

What Did You Watch in July?

Nearly 27,000 people are now subscribed to my YouTube channel. On my channel I publish screencast videos about all kinds of things including how to make videos, how to do interesting things with Google Slides, how to publish a podcast, and many other topics. Most of the videos are made to address questions that people send to me.

YouTube provides channel owners with interesting statistics about their channels. Some of those statistics include the cumulative time spent watching videos, the time spent watching individual videos, and the average length of time spent viewing videos on the channel. Based on that information, the following were the five most popular videos on my channel in July.
